Thats awesome thanks Martin. Trying to work out the correct mastery cyl diameter for the twin Grimeca's on the Harley...this helps a lot...Glad it helps.The relationship between sizes is sometimes counter intuitive, I had a Norton Commando for almost 30 years, originally they put on a larger bore master cylinder as they didnt want people locking front brake.Later owners sleeved cylinder down to get improved feel and braking.Obviously with rear sets the leverage changes with the distance force applied from pivots (fulcrum)I knew they taught me all about it at Technical College for a reason, just didnt realise at the time
